METHOD FOR WITHDRAWING MATERIALS FROM HIGH SPEED ROTARY FURNACES Filed April 15. 1956 Patented June 2&19333 allelic Georg Zotcs, Berlin, Germany Application April 15, 1936, Serial No. '34,.515 Germany April 23, 1935 3 claims. (or. ace-st) This inventon relates to a method of and means for withdrawing materials from high-speed rotary furnaces of the kind wherein the molten material is maintained by centrifugal force as a cylinder which lines the wall of the rotary furnace drum.
The discharge of materials from the furnace is usually efiected by lettingit overflow at one end of the and it has also been proposed to withdraw material from the furnace by means of a suction pipe. I
The object of the present invention is to obtain a discharging method allowing simple means to be employed for withdrawing materials from any desired portion of the liquid or viscous cylinder and for a complete emptying of the drum, and the invention consists essentially in inserting a discharging element more or less deeply into the revolving cylinder iorrned by the molten material so as to divert material, under the" infiuence of the movement of the cylinder, from the latter through the discharging element.
The discharging element may consist of a channelled or tubularmember together with sup-'- porting means for said member allowing rapid universal adjustment thereof during the operation, so that it can be shifted for taking material from the desired portion of the liquid or viscous cylinder. Fig. 1 of the accompanying drawing represents a side view of a device for carrying out the invention, the revolving drum being shown in section,
Fig. 2 is a, cross-section on the line IIII of Fig. 1.
The furnace comprises an open ended, substantially horizontal drum 9, made of or lined with refractory material, into which all material for the manufacture of glass or the like isie'd together with a heating flame whereby the mate-.
rials .are fused and rendered liquid or viscous. The drum is rotated at a high speed, so that the material will be distributed over the inner wall of the drum as a cylinder 3, the drum being provlded with end flanges It for retaining the materials within the drum. v v v For discharging the molten material from the dipping said end into the surface of the cylinder The discharging member is made of fireproof it is essential that the discharging member should be "capable of rapid and convenient universal adjustment during the'operation. By this arrangement, therefore, the discharging member will be also readily adaptable for a satisfactory dischar geof materials under all-charging conditions of the furnace. r
Suitable constructions of the device may naturally be resorted to. For instance the discharging member may be suspended in a movable manner 2.
The discharging member may be adapted to deliver into one furnace the material discharged from another furnace.
I wish it to he understood that I do notdesire to be limited to the exact details of operation shown and described, for obvious modifications will accur to a person skilled in the art.
I claim:
l. A method oi discharging molten-material through a channelled discharging member from a cylindrical furnace, consisting in rotating the furnace about a horizontal axis to form the molten'material by centrifugal action into a hollow cylinder, inserting one end of the discharging member into the revolving cylinder, and
with the mouth of the member set against the movement of the material for diverting the latter through the member.
2. A method of discharging molten material through a channelled discharging member from a cylindrical furnace, consisting in rotating the "furnace about a horizontal axis to form the drum, 8. discharging element in the form ofa' tubularor channelled member l is provided which is adapted to enter the'drumand to dip with its end 2 more or less deeply into the cylin-a der 3, preferably at the top portion thereof at the descending side of the vertical centre line, as
shown in Fig. 2. Where the discharging member dips into the cylinder 3, material will be diverted ,from the cylinder owing to the movement of the latter and mode to flow through the member from which it is collected at t.
molten material by centrifugal action into a hollow cylinder, inserting one end or thedischarging member into the revolving cylinder, and dipping said end into the descending part of the inner surface of the cylinder with the mouth of the member set against the movement of the material for diverting the latter through the member. 3. A method of discharging molten material through a channelled discharging member firom' a cylindrical furnace, consisting in rotating the furnace about a horizontal axis to form the molten material by centrifugal action into a hollow cylinder, inserting one end of the discharg- 'ing member into the revolving cylinder, and
dipping'said end into. the descending part of the inner surface or the cylinder, 'ne'arthe top there= of, with the mouth. 01' the member set against .the movement of the materlalfor diverting the latter through the member.
